When natural rubber is heated with 3-5% sulphur,it becomes non-stricky and more elastic.This process is called vulcanisation,which gives better tensile strength,elasticity and resistance to abrasion than natural rubber.This is due to sulphur cross links between polymer chains.
Hence (c) is the correct answer.
